Need to enhance the video quality

[raj11]

Hi Friends,

This time I am again here for some help; I bought a DVD with much expectation regarding the quality.

I was waiting for ripping the DVD; but its my bad luck as the video quality is worst;

I have attached .m2v file.

Please friends, help me out; Please provide with proper filters so that I can get excellent quality of this movie.

N.B.: I am using Megui; create AVS file, then rip dvds.

Thanks in advance...

That will never happen. It's from an analog source, maybe a PAL VHS tape originally. The first thing you should do is remove the field blending:

Yadif(Mode=1)#or a better bobber, one such as QTGMC
Srestore()

Thanks for the reply; but I am already using these two. Have a look:

yadif(mode=1, order=0)
srestore(23.976)

Please let me know how I can atleast make the pic quality better.. waiting for someone's solution...

Look at what? You setting the wrong framerate and making it play jerky? Why would I want to look at that? It's field-blended from a PAL source, not a film source.

Ooppss!! means I am using wrong frame rate..
Please help me out @manono.. What I have to do then?

If you want to remove the blue tint, add in some yellow. If it's too soft, sharpen it. But first things first - get the 'base' framerate right.

Sure... I am changing the frame rate. Now pls let me know how can I sharpen this quality?

The quality will always suck. Take your pick. I usually use Limited Sharpen Faster:

Using QTGMNC and sRestore I get 25fsp with no frame blending, but the color and levels are a mess. Darks are crushed and murky, highlights blown out. Real problem. Needs some denoising and resize if you want PAL DVD.

@sanlyn, thanks for your valuable comments. I have also understood the condition of the DVD; now your detailed explanation added a extra to this.

Now in this situation, I wanna get a standard picture quality with more brightness & contrast so that this time I can get relief.

Well...there are frame problems. I used stab() to calm most of the frame hopping, but you still see some shudder, bent forms, objects twisting, etc. Actually not much noise. Oversharpening low-bitrate video makes it look extremely odd, especially on TV: plastic, easy to get halos, etc. The problem is that low bitrate has no detail to begin with. All one can do is over-enhance edges, which looks strange because the objects have no "inner" detail.

Many severe color problems. Someone wrecked the basic colorspace. Colors will never look quite correct. And it appears auto-color gadgets were used in the process -- in the source you can see color and levels change when the camera moves. The PAL mpg attached also had some image repairs (source is on the left, sample effort mpg is on the right):

RemoveSpots() cleaned many spots and dots, such as this white cherry bomb on the left-hand border:

ReplaceFramesMC used on 12 frames in this sample, for multiple scratch marks, bombs, and dots:

And manual patches, as to patch in part of a clean section from another frame (not always possible):

It would take many weeks of constant effort to fix this video -- possibly months. I'd look for a clean copy of the movie. The MPG sample below was encoded as progressive PAL, almost twice the size of the low bitrate source. Increasing bitrate can't "improve" low bitrate sources, it just helps prevent worsening. There is still some stutter and odd motion now and then, mainly because the party that made the source did their best to ruin it.

You should learn to look at video more closely. Your sample clip is already too bright and has too wide a range of contrast. That's one reason why it looks so strange, and why it is difficult to correct. It doesn't help that the original colorspace has been damaged somehow.
